Okay guys I might starting making a new story but I'm not really sure who the main character should be.

This is the description:
Humans are such fragile creatures. One moment they’re alive and in the next they could be dead. The population has begun to die out. Someone or something is killing them and only the angels are being left untouched. Who or what is doing it? What the angels don’t know is that it is only the beginning of a new world to come.

Who do you think should be the main:

• Luhan
• Chen
• Baekhyun
• Kai

Comment your response :) THANKS

Thanks guys. LUHAN will be the main character, but the others will also play important roles in the story. THanks for your help :)
